totaly binary incomnpatible change:

Mon Jul  6 18:30:48 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtkbutton.h:
        * gtk/gtkbutton.c: GtkButtons are now derived from GtkBin. we mirror
        GTK_BIN (button)->child to button->child to keep source compatibility.

        * gtk/gtkoptionmenu.c:
        * gtk/gtkclist.c:
        * gtkcheckbutton.c: don't refer to button->child, but
        GTK_BIN (button)->child instead.
